I have MSP430F5419A microrontroller and SIM908 GSM/GPRS modem. It's given in SIM908 manual that it supports CMOS level.
Do i need a level shifter to connect with MSP430?
In case no level shifter is required, Which pins should i use in MSP430(DTE) to connect to RTS,CTS, DTR, DCD and RI pins of modem(DCE)?
